O’Mara Air Diverters and Dampers are engineered to manage airflow, pressure, and material routing in grain handling and bulk processing systems. Designed for reliability and long service life, these components help prevent moisture issues, reduce dust, and keep your operation running smoothly—bin after bin, shift after shift.
Whether you’re filling multiple bins, unloading from dryers, or managing pneumatic conveying air, O’Mara air diverters deliver precise control where it matters most.
An air diverter or air damper is a mechanical device used to regulate, redirect, or block airflow and convey air in grain and bulk material systems.
They are commonly installed on:
These devices allow air to vent safely, prevent backflow, and redirect material and air to the correct destination without shutting down the system.
During bin filling, backflow air needs a way to escape. Air diverters relieve pressure to prevent:
Backdraft dampers block warm, moist air from dryers from traveling upstream. This helps prevent:
Hopper-top air diverters allow operators to:
In pneumatic systems, diverters manage both product and air, so conveying velocity remains consistent while excess air is routed to remote filters.
By stopping the movement of moist air, these systems keep dust dry and flowing even in cold or humid environments.
Operators can change fill points without stopping conveyors or blowers, reducing downtime and increasing throughput.
Hopper-top diverters can route air to centralized filters, cutting:
Controlled airflow reduces kernel impact, improves grain distribution, and helps maintain uniform bin leveling.
Dust-tight seals help control airborne dust, improving housekeeping and operator safety.
O’Mara air diverters and dampers are built for demanding environments.
Each unit is engineered to match your material, airflow volume, and system layout.
No two facilities are the same. O’Mara designs air diverters and dampers to fit your operation and not the other way around.
We consider:
The result is a solution that installs cleanly and performs reliably from day one.
Every O’Mara air diverter and damper is designed by experienced American engineers and manufactured in the USA. Built by people who know grain handling and know what it takes to make equipment last.
From material selection to fabrication and final assembly, quality is controlled at every step. The result is durable, long-lasting airflow control equipment you can trust to perform season after season with responsive support from a team that stands behind what it builds.
With decades of experience designing and manufacturing equipment for seed, grain, and bulk processing plants, O’Mara brings practical engineering to every project.
Our in-house team handles:
From single diverters to complete plant systems, we build equipment that works in the real world.
If airflow, moisture, or dust is limiting your system performance, an O’Mara Air Diverter or Damper can make the difference.
Let our team design the right solution for your bins, dryers, and conveying lines.
